You'll be pleased to learn that there are at least two known solutions to General Relativity that allow time travel. The first requires the universe to be rotating (at present, it isn't) so that you can send your spaceship off in a particular direction, you'll travel in time. So all you need to do is go back in your time machine and tinker with the big bang so that we end up with a rotating universe. Simples! But I can't help but feel I've missed something obvious here...
The other is to get a rotating cylinder of neutronium (the same material that neutron stars are made of.. and, @chriss2.0 neutron stars and black holes are very well described by General Relativity): that generates areas where time goes backwards. So all you need to do is take the sun, compress it into a cylinder 10 km in diameter and 50 km long and spin it so that its surface is travelling at close to the speed of light. You're probably not going to be able to fit that into the garden shed, though. And you may get people complaining about the lack of sunlight, lack of crops and the oceans and atmosphere freezing. You know, small pesky inconsequential details and stuff. Just tell them that they're luddites who're standing in the way of Progress, that'll sort them.

Its the "American Way" of pronouning their words that did it, caused the confusion.

ur right about neutron stars ,(would you believe i was thinking of neutrinos when i said that, i know they are nothing alike but hey they sound the same
) (im bad like that once in a bike vid revew, i called the pedals, handlebars. i didnt catch on till ppl took the mik)however be careful when using the definition nutronium around scientific community because there is no universally agreed-upon definition for the term neutronium.
also the problem with e=mc2 as it requires mass, and string theory would suggest that a black hole would either have no mass or infinite mass, and if you come across infinity in string theory, your calculations are considered a failure,
as according to the string theory, infinity cannot exist, it is not quantifiable ,
therefore black holes cannot exist, but we well know they do. bit of a headache.
as far as my understanding goes, other theory's regarding what black holes actually are, may be able to squeeze Eisensteins theory in, for example if indeed as some believe, that a black hole is basically a factory for breaking down matter in to energy then maybe it could apply hear.
but the problem in this is that a black hole requires mass to create a strong gravitational force, and unless there is another form for matter to exist, in that would allow more density, black holes are far to small for the gravitational energy they create for e=mc2 to apply hear

ive been thinking! ouch, curent thoughts are that we live in spacetime space and time being the same thing. so if we travel in space we travel in time, so in the sence that we/i as a child thought about time travel,as going forward or back in time alone, thats not possible.but as an aside as more time passes so more space comes into exsistance? hehe explains the expasntion of the univers, however i am normall wrong but these are the thought of canal leg steve! withour beer, and i feel its only fair to have them again with beer to make a comparison

Beer, wonderful stuff isn't it?

see... i used to insist gigabytes should be pronounced with a soft G because... well, Dr Emmet Brown is right so just don't think of accusing him of any mispronunciation. Just got funny looks
, hence 'used to insist'.

I actually meant that in the film it's pronounced jiggerwatts.
